I think the whole "4th Reich" urban myth's would fit perfectly into the cinematic marvel universe, with Red Skull as the new leader after Hitler bites the bullet. And either of these locales would be a great place for Red Skull to lay low while the medical science is invented to keep him alive so long. How in your face and awesome of a twist would it be if the only thing around that cap can still relate with are the Nazis? This could also lead into an awesome Ultimate Liberators(or whatever they were called, ultimates 2 vol. 2) like storyline with Nazi "super heroes", which may or may not be similar to the Avengers.
